The IdentifyInputFields is used to retrieve the fields in the hidden variable (to be signed).

This is only done when using the iSeries Web Server and it is a workaround because the iSeries does not support recursive calls.

The eventhandler can not call itself, so it calls the IdentifyInputFields, which then calls the eventhandler.

The IdentifyInputFields is also used by the DocumentTemplateGenerator to retrieve fields to process.
